-- Information about the crash:
- What I was doing when the application crashed:

The Latte Dock crashes immediately on system startup. However, when launched manually after that, it no longer crashes.

Currently using the Edna Layout without the sidebar (https://store.kde.org/p/1417204/)

The crash can be reproduced every time.

-- Backtrace:

Comment 1 Michail Vourlakos 2021-06-11 20:59:32 UTC 
Use default layout and report of it still crashes.

Most crashes come from faulty applets
Comment 2 abhiroop.santra 2021-06-12 05:49:12 UTC 
Hi,

Using the default layout does not crash.

now you can add your applets one by one until you find which one crashes.
Comment 4 abhiroop.santra 2021-06-12 21:44:14 UTC 
The crash happens because of the widgets in edna layout (https://store.kde.org/p/1417204/)
